Abstract

The invention relates to the technical field of film laminating machines, and particularly discloses a double-sided film laminating machine. The double-sided film laminating machine comprises supporting frames which are symmetrically arranged, a thin film roller which is rotationally connected between the supporting frames in an up-down symmetrical mode, a plurality of transmission rollers which are rotationally connected between the supporting frames and can drive a printed product to move, and a driving mechanism which can drive the thin film roller and the transmission rollers to rotate, wherein guide blocks are further connected between the supporting frames in an up-down symmetrical sliding mode; cavities are formed in the guide blocks; motors are fixedly connected in the cavities; output shafts of the motors are coaxially connected with transmission gears; the transmission gears are symmetrically meshed with racks; the free ends of the racks are fixedly connected with connecting rods; the free ends of the connecting rods extend out of the guide blocks and are provided with push plates capable of being pushed on the surface of a thin film; air bags are arranged in the cavities; the connecting rods are fixedly connected with piston rods; one end of each piston rod extends into the corresponding air bag and is connected with a piston in a sliding and sealing mode; and air inlet holes and air outlet holes are formed in the side walls of the guide blocks. The problem that in the film laminating process of a traditional double-sided film laminating machine, the thin film is prone to wrinkling, and the film laminating effect is affected is solved.

Description

technical field

[0001] The application relates to the technical field of laminating machines, and specifically discloses a double-sided laminating machine. Background technique

[0002] The laminating process is a surface processing process after printing, also known as post-press laminating, post-press laminating or post-press filming, which refers to covering a layer of 0.012-0.020mm on the surface of the printed matter with a laminating machine Thick transparent plastic film forms a paper-plastic product processing technology. The laminating machine is the equipment used to complete the laminating process. The laminating machine can be divided into a ready-to-coat laminating machine and a pre-coating laminating machine. There are two types, which are special equipment for paper and film, that is, the coating type laminating machine includes three parts: gluing, drying, and hot pressing. It has a wide range of applications and stable and reliable processing performance. It...
